UNITED STATES PATENT GEEICE- y LOUIS G. CHAPUT, OF NEW YORIL-N. Y.

IMPROVEMENT 1N PRINTERS cHAsEs.

Specification forming part of Letters Patent No. 139, 542, dated June 3,1873; application ed May 13, 1873.

To all whom it may concern:

Be it known that I, LoUIs GEORGE OHAPUT, of the city, county, and Stateof New York, have invented a new and useful Improvement in PrintersChase; and I do hereby declare the following to be a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference being had to the accompanying drawingforming a part of this specification, in which drawingv Figure 1 is aplan view of my improvement. Fig. 2 is a section in the lineman of Fig.1, showing a modification in the form of the joint `between the outercha-se and the frame of the inner chase.

.Similarletters indicate corresponding parts.

This invention relates to av printers chase; and consists in an innerchase adapted and arranged to be placed inside of an ordinary chase, sothat the latter can be used, when combined with the inner chase, forprinting' cards and doing other small Work, and most of the furnitureand quoins heretofore required in using au ordinary chase for small workare dispensed with. My invention is meant to gain economy in printing byenabling one to dispense with most of the furniture and quoins nowrequired, and yet use a chase of the full capacity of whatever pressrone is working, without changing the press or the chase when printingfrom small forms. My improvement accomplishes this result in a simpleand inexpensive manner by supplying a supplemental inside chase which isprovided with arms that are fitted within the main chase in such amanner as substantially to form therewith a single structure, the ends`of the arms interlocking with the angles of the main chase, so that theinner or supplemental chase is both centered and rigidly held in themain chase.

The letter A designates au ordinary chase, and B the inner orsupplemental chase above mentioned. The chase B is provided at itscorners with arms U C C G, which interlock with the angles D D D D ofthe chase A, as shown in the drawing, so that the combined apparatus issubstantially united in one, so far as is necessary for the printingprocess. The joint, at the points of contact between the arms C and theanglesof the main chase, is so made as to allow the main chase A to belifted and removed without .disturbing the shown in the drawing, theangles ofthe main .i chase being beveled on the under side to correspondthereto, or the arms can be provided with rabbets which shall tit intosuitable recesses made on the under side of the main chase in itsangles, or the parts may be interlocked or connected in. any otherconvenient manner. The supplementary chase can be provided withpermanent wedge-shaped strips of furniture, E, as here shown, when iirstmade, or can, if preferred, be left with straight sides.

Supplementary chases B, for forms of different sizes and shapes, can beprovided according to my invention, their arms being arranged in eachcase to tit within the anglesof the main chase, so that a job printerhaving a chase, A, of full size for the capacity of his press, can, withthe aid of my invention.l make use of such press and chase for smallforms, and forms of various sizes and shapes, with only such furnitureandquoins as are necessary to lock up the form in the inner chase B,thereby saving much` expense and outlay of capital, as well as time, andincreas ing the capa-city of his office.

What I claim as new, and desire to secure by Letters Patent, is-

The supplementary or inner chase B provided with arms C, arranged tointerlock with the angles or sides of the main chase A, substantially asdescribed. Y

This specification signed by me this 21st day of April, 1873.
